This document proposes a system to provide security for DNS using cryptography. It discusses using a pseudo-random number generator instead of RSA to quickly generate key pairs. The proposed system uses message digest and digital signatures with the private key to encrypt and sign messages. It would include modules for key generation, encryption/decryption, signature creation and verification. The system aims to provide faster and more secure DNS services compared to existing systems that are error-prone with low speeds.

KHNOG 3: DDoS Attack Prevention
APNIC Security Specialist Jamie Gillespie presents on DDoS Attack Prevention at KHNOG 3, held online on 4 December 2021.
Certificates and Web of Trust
The document discusses certificates and alternatives to the hierarchical trust model used for SSL certificates. It describes how SSL works using certificates authorities (CAs) to validate website certificates. Problems are discussed with this approach, including vulnerabilities of the CA system. Alternatives presented include PGP's web of trust model, where users decide who to trust, and the Perspectives browser add-on, which keeps a record of certificate changes to detect attacks. The document advocates for a decentralized trust model rather than relying solely on CAs.
SECURE CLOUD STORAGE FOR REMOTE MOBILE DATA COLLECTION, Federico Mancini, UiB
SECURE CLOUD STORAGE FOR REMOTE MOBILE DATA COLLECTION, Federico Mancini, UiBThe Research Council of Norway, IKTPLUSS
This document proposes a secure cloud storage solution for mobile data collection in remote areas with limited infrastructure. It discusses using encryption to securely store data in the cloud while keeping decryption keys locally on mobile devices. The proposed system encrypts data with randomly generated keys, encrypts the keys with a master key derived from the user's password, and uploads everything to the cloud. This allows access to encrypted data while preventing offline password cracking. It also includes a key recovery process using Shamir's Secret Sharing to backup encrypted master keys. Overall, the system aims to securely store collected mobile data in the cloud while protecting against various threats.BlueHat v17 || 28 Registrations Later: Measuring the Exploitation of Residual...

Any individual that re-registers an expired domain implicitly inherits the residual trust associated with the domain’s prior use. We find that adversaries can, and do, use malicious re- registration to exploit domain ownership changes—undermining the security of both users and systems. In fact, we find that many seemingly disparate security problems share a root cause in residual domain trust abuse. With this study we shed light on the seemingly unnoticed problem of residual domain trust by measuring the scope and growth of this abuse over the past six years. During this time, we identified 27,758 domains from public blacklists and 238,279 domains resolved by malware that expired and then were maliciously re-registered. To help address this problem, we propose a technical remedy and discuss several policy remedies. For the former, we develop Alembic, a lightweight algorithm that uses only passive observations from the Domain Name System (DNS) to flag potential domain ownership changes. We identify several instances of residual trust abuse using this algorithm, including an expired APT domain that could be used to revive existing infections. Web Security and SSL - Secure Socket Layer
Transport Layer Security (TLS), and its now-deprecated predecessor, Secure Sockets Layer (SSL), are cryptographic protocols designed to provide communications security over a computer network. Several versions of the protocols find widespread use in applications such as web browsing, email, instant messaging, and voice over IP (VoIP). Websites can use TLS to secure all communications between their servers and web browsers.

BlueHat v17 || A Lustrum of Malware Network Communication: Evolution and Insi...BlueHat Security Conference
Chaz Lever, Georgia Institute of Technology
Both the operational and academic security communities have used dynamic analysis sandboxes to execute malware samples for roughly a decade. Network information derived from dynamic analysis is frequently used for threat detection, network policy, and incident response. Despite these common and important use cases, the efficacy of the network detection signal derived from such analysis has yet to be studied in depth. This paper seeks to address this gap by analyzing the network communications of 26.8 million samples that were collected over a period of five years.
Using several malware and network datasets, our large-scale study makes three core contributions. (1) We show that dynamic analysis traces should be carefully curated and provide a rigorous methodology that analysts can use to remove potential noise from such traces. (2) We show that Internet miscreants are increasingly using potentially unwanted programs (PUPs) that rely on a surprisingly stable DNS and IP infrastructure. This indicates that the security community is in need of better protections against such threats, and network policies may provide a solid foundation for such protections. (3) Finally, we see that, for the vast majority of malware samples, network traffic provides the earliest indicator of infection—several weeks and often months before the malware sample is discovered. Therefore, network defenders should rely on automated malware analysis to extract indicators of compromise and not to build early detection systems. MTLS in a Microservices World
One obvious side effect of migrating to a microservices architecture is the need for infrastructure automation. Unfortunately, most automation systems do not take security into consideration, making production deployments orders of magnitude more complex than the initial testbed deployment.
The perfect example of this steep increase in deployment difficulty is the creation and management of Public-Key-Infrastructures (PKI). Even though the use of TLS Certificates for service to service communication is known as a best-practice, very few companies actually deploy their systems using mutually-authenticated TLS connections.
In this talk I will go over why TLS is the right solution for service to service communication, describe ways to automate the creation and management of your PKI, and present in detail how Docker's swarm orchestration system bootstraps and manages individual node certificates.
SSL/TLS 101
SSL/TLS 101 provides an overview of SSL and TLS including:
1) SSL and TLS are cryptographic protocols that provide security for internet communications like HTTPS and HTTP/2. They provide confidentiality, integrity, and authentication.
2) Key concepts of SSL/TLS include symmetric encryption for confidentiality, public key cryptography for key exchange, digital signatures for authentication, and X.509 certificates issued by certificate authorities to verify identities.
3) The document reviews the history and versions of SSL/TLS, how the core requirements of confidentiality, integrity and authentication are achieved, and references for further reading on implementing SSL/TLS.
Secure Socket Layer (SSL)
SSL is an internet protocol for secure exchange of information between a web browser and a web server.
What is SSL ? The Secure Sockets Layer (SSL) Protocol
SSL is a protocol that allows clients and servers to securely communicate over the internet. It uses public-key encryption to authenticate servers, optionally authenticate clients, and establish an encrypted connection to securely transmit data. The SSL handshake allows the client and server to negotiate encryption parameters to generate shared secrets and session keys, which are then used to encrypt all further communication during the SSL session. Common implementations of SSL include OpenSSL and Apache-SSL.

Electronic mail security
PGP and S/MIME are two standards for securing email. PGP provides encryption and authentication independently of operating systems using symmetric and asymmetric cryptography. S/MIME uses X.509 certificates and defines how to cryptographically sign, encrypt, and combine MIME entities for authentication and confidentiality using algorithms like RSA, DSS, and 3DES. DKIM allows a sending domain to cryptographically sign emails to assert the message's origin and prevent spoofing, while the email architecture standards like RFC 5322 and MIME define message formatting and how attachments are represented.
Defend Your Data Now with the MITRE ATT&CK Framework
MITRE is a not-for-profit organization that operates federally-funded research and development centers. Their ATT&CK framework is a useful cybersecurity model illustrating how adversaries behave and explaining the tactics you should use to mitigate risk and improve security. ATT&CK stands for “adversarial tactics, techniques and common knowledge.”
This presentation explores a methodology for pairing proven industry frameworks like MITRE ATT&CK with threat modeling practices to quickly detect and respond to cyber threats. With this approach, industrial organizations can slice their infrastructure into smaller components, making it easier to secure their assets and minimize the attack surface.
Takeaways include how to:
-Make the most out of their threat intelligence feeds
-Report on progress and compliance
-Negotiate trust relationships in the intelligence sharing cycle
-Improve their organization’s overall security posture

Literature Survey: Secure transmitting of data using RSA public key implement...
This document discusses techniques for secure and fast transmission of data in mobile ad hoc networks (MANETs). It proposes using identity-based cryptography with visual cryptography. For identity-based cryptography, the RSA cryptosystem is used to generate public and private keys, with Vedic mathematics adopted for fast calculations. Vedic mathematics allows for faster prime number calculations compared to modern mathematics. Visual cryptography allows images to be encrypted and decrypted by the human visual system without computation. The techniques aim to securely and efficiently transmit encrypted images and data in MANETs.
Encryption And Decryption
This document discusses encryption and decryption. It was developed by four students and submitted to their professor. The document introduces encryption as converting plaintext to ciphertext and decryption as converting ciphertext back to plaintext. It explains that encryption uses a key to scramble the plaintext and decryption uses the same key to unscramble the ciphertext to retrieve the original plaintext. The document also briefly mentions the feasibility study, methodology, purpose of providing security, and system requirements for the encryption/decryption software.
Security of DNS
Here are the key steps in a KSK double signature rollover:
1. The child publishes the new KSK alongside the existing KSK.
2. The child asks the parent to sign the new KSK.
3. Once signed by the parent, the child removes the existing KSK signature and relies solely on the new KSK signature.
The interaction between child and parent allows the parent to securely validate the new KSK. This prevents roll over without authorization.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Major project presentation
- 1. SECURITY SYSTEM FOR DNS USING CRYPTOGRAPHY
- 2. OBJECTIVE To provide security by combining the concept of both the Digital Signature and Asymmetric (public key) cryptography by sending the Public key over the Network.
- 3. Overview of DNS The DNS translates Internet domain and host names to IP address. DNS automatically converts the names we type in our Web browser address bar to the IP addresses of Web servers hosting those sites. The mapping or binding of IP addresses to host names became a major problem in the rapidly growing Internet and the higher level binding effort went through. We got the different stages of development up to the currently used Domain Name System.
- 5. EXISTING SYSTEM The existing system is manually maintained. It uses RSA Algorithm for key generation. Since it uses RSA Algorithm it is necessary to provide two Prime numbers to generate Key Pair which results in Mathematical and Brute force attack. It sends the Public key through the Network. Time consumption Low reliability DISADVANTAGES Error prone Less operational speed Low speed communication
- 6. The Following function avoids the pitfalls of the existing system Fast and efficient work Ease of access to system Manual Effort is reduced
- 7. PROPOSED SYSTEM Taking the security into consideration the best solution is using Pseudo Random Number Generator for generating Key Pair in a quick and more secured manner. Use of MD5 (or) Message Digest and Compressing the message. Signature is created using Private Key and Message Digest which is transmitted along with the Public Key. The transfer of the packets from each System to System is shown using Graphical User Interface (GUI).
- 8. ADVANTAGES OF PROPOSED SYSTEM They are not limited to 1024 bits like DSA They can use hash longer than 160 bits.
- 10. IMPLEMENTATION Authentication Message Encryption using Message Digest Algorithm Key Generation using PRNG Algorithm Signature Generation Verifying Signature and Decrypting
- 11. MODULES Key Generation Encryption and Decryption Signature Creation Signature Verification
- 12. MODULE DESCRIPTION KEY GENERATION Taking two prime numbers Generating random numbers Generating public and private keys The key pair (public and private key) is generated using the Cryptography PRNG (Pseudo Random Number Generator) Algorithm.
- 13. Key Generation Module Design PRNG ALGORITHM CALL THE METHOD IN THE CODING GENERATE TWO RANDOM NUMBERS (PUBLIC AND PRIVATE KEY) DISPLAY THE KEYS IN THE BACK END GENERATE SIGNATURE AND SEND
- 14. AUTHENTICATION ENTER THE USER NAME AND PASSWORD AUTHENTICATION VERIFY TEXT FILE LOGIN SEND MESSAGE OR ATTACHMENT
- 15. MESSAGE ENCRYPTION MESSAGE DIGEST ALGORITHM CONVERT EACH CHARACTER TO ASCII CODE CONVERT THE ASCII CODE TO HEX CODE ENCRYPTED MESSAGE READ CHARACTER BY CHARACTER
- 16. SIGNATURE GENERATION DSA ALGORITHM PRIVATE KEY + ENCRYPTED TEXT FILE GENERATE SIGNATURE PUBLIC KEY + SIGNATURE SEND THROUGH THE NETWORK
- 17. VERIFYING SIGNATURE AND DECRYPTING DESTINATION PUBLIC KEY ,SIGNATURE FROM THE SENDER GENERATE SIGNATURE USING DSA ALGORITHM DECRYPT THE MESSAGE OR FILE REPLY TO THE SOURCE VERIFY THE SIGNATURE IF MATCHES DISCARD NO MATCH
- 18. ATTACK ON ROOT SERVER OCTOBER 23, 2012 Attack on root servers 9 out of 13 servers were down Slowdown after 8 or more servers are down No noticeable slowdown observed by users
- 19. ATTACK ON MICROSOFT 22.5 hour outage of web sites Series of attacks on Name servers, Jan 2001 Reasons – attack or misconfiguration Intermittent access to Microsoft.com, MSN.com $200 million advertising campaign Microsoft Web sites drew 54 million unique visitors in December
- 20. DNS SECURITY EXTENSION Idea: Add a digital signature to each Name Information – Signing with the zone’s private key – Authenticating with the zone’s public key Main issue – Key genereation – DNS as Public Key Infrastructure
- 21. SYSTEM REQUIREMENTS HARDWARE REQUIREMENTS PROCESSOR III AND ABOVE 20 GB HARD DISK 256 DDR RAM SOFTWARE REQUIREMENTS MICROSOFT.NET FRAMEWORK 1.1 INTERNET INFORMATION SERVER BROWSER(I E OR NETSCAPE)
- 22. CONCLUSION: The security threats for DNS was overcome by using public key validation and it was implemented and executed successfully
